$Log$
Revision 1.13  2006/12/07 08:51:26  jgrosseo
update (alberto):
table, db names in ldap configuration
added GRP preprocessor
DCS data can also be retrieved by data point

Revision 1.12  2006/11/16 16:16:48  jgrosseo
introducing strict run ordering flag
removed giving preprocessor name to preprocessor, they have to know their name themselves ;-)

Revision 1.11  2006/11/06 14:23:04  jgrosseo
major update (Alberto)
o) reading of run parameters from the logbook
o) online offline naming conversion
o) standalone DCSclient package

Revision 1.10  2006/10/20 15:22:59  jgrosseo
o) Adding time out to the execution of the preprocessors: The Shuttle forks and the parent process monitors the child
o) Merging Collect, CollectAll, CollectNew function
o) Removing implementation of empty copy constructors (declaration still there!)

Revision 1.9  2006/10/02 16:38:39  jgrosseo
update (alberto):
fixed memory leaks
storing of objects that failed to be stored to the grid before
interfacing of shuttle status table in daq system

Revision 1.8  2006/08/15 10:50:00  jgrosseo
effc++ corrections (alberto)

Revision 1.7  2006/07/20 09:54:40  jgrosseo
introducing status management: The processing per subdetector is divided into several steps,
after each step the status is stored on disk. If the system crashes in any of the steps the Shuttle
can keep track of the number of failures and skips further processing after a certain threshold is
exceeded. These thresholds can be configured in LDAP.

Revision 1.6  2006/07/19 10:09:55  jgrosseo
new configuration, accesst to DAQ FES (Alberto)

Revision 1.5  2006/07/10 13:01:41  jgrosseo
enhanced storing of last sucessfully processed run (alberto)

Revision 1.4  2006/06/12 09:11:16  jgrosseo
coding conventions (Alberto)

Revision 1.3  2006/06/06 14:26:40  jgrosseo
o) removed files that were moved to STEER
o) shuttle updated to follow the new interface (Alberto)

Revision 1.7  2006/05/12 09:07:16  colla
12/05/06
New configuration complete

Revision 1.2  2006/03/07 07:52:34  hristov
New version (B.Yordanov)

Revision 1.4  2005/11/19 14:20:31  byordano
logbook config added to AliShuttleConfig

Revision 1.3  2005/11/17 19:24:25  byordano
TList changed to TObjArray in AliShuttleConfig

Revision 1.2  2005/11/17 14:43:23  byordano
import to local CVS

Revision 1.1.1.1  2005/10/28 07:33:58  hristov
Initial import as subdirectory in AliRoot

Revision 1.1.1.1  2005/09/12 22:11:40  byordano
SHUTTLE package

Revision 1.3  2005/08/30 09:13:02  byordano
some docs added
